How do you mean ``don't work''?  You should see the first character of the
composition, IIRC.  If that doesn't work, perhaps there's some bug.

That's possible, but I think having a command that deletes the base
character together with its diacriticals is better.  Perhaps Thai and
Tibetan users will like it too ;-)  It's even possible that there is such a
command already.
